Well, I finally finished my build! That lower sat all finished waiting for the upper to come in for over a month. Not to mention that I bought parts and the lower over a 3 month period. Here is the list: PSA lower RRA LPK VLTOR IMOD stock PSA striped upper YHM 1:7 barrel 16" YHM free float, rifle length diamond rail Leatherwood CMR 1-4 optic with Burris PEPR mount. This is my first, I was planning to order a complete upper but my LGS talked me into building. He was great and let me use all of his tools and guided me through the upper build. If anyone is in Tampa, fl area hit me up, he is new and his prices are fantastic. Best part is he is not some GI Joe cowboy pr!ck like so many other gunshop owners can be (at least around here)! I hope the pics post, haven't done this either on the phone. Range report after the weekend, I have a lot of ammo to put together! Ryan...RLTW!
